Book Description

This book introduces advanced thyristor-based shunt hybrid active power filters (HAPFs) for power quality improvement in power grids, which are characterized by a low dc-link operating voltage and a wide compensation range. This means they can overcome the high dc-link voltage requirement of conventional active power filters and the narrow compensation range problem of LC-coupling hybrid active power filters. Consisting of 10 chapters, the book discusses the principle, design, control and hardware implementation of thyristor-based hybrid active power filters. It covers 1) V-I characteristics, cost analysis, power loss and reliability studies of different power filters; 2) mitigation of the harmonic injection technique for thyristor-controlled parts; 3) nonlinear pulse width modulation (PWM) control; 4) parameter design methods; 5) minimum inverter capacity design; 6) adaptive dc-link voltage control; 7) unbalanced control strategy; 8) selective compensation techniques; and 9) the hardware prototype design of thyristor-based HAPFs, verified by simulation and experimental results. It enables readers to gain an understanding of the basic power electronics techniques applied in power systems as well as the advanced techniques for controlling, implementing and designing advanced thyristor-based HAPFs.

Book Description

Active power filters can be used for harmonic elimination, reactive current compensation, and clean delivery of power. The basic principle of APF is to produce a compensation current which is of the same amplitude and opposite phase with harmonic currents and to eliminate unexpected harmonic currents. The shunt APF could compensate the harmonics generated by the load current through injecting compensation current to the grid. This book will have a large potential readership, ranging from scientists and students of wide disciplines to electrical engineers. It is an essential read for engineers and scientists working in the fields of power electronics and active power filters and advanced control technologies. It will also be of interest to senior undergraduate and graduate students as well as aerospace, mechanical, electrical design engineers who want to acquire some background in the advanced control of active power filters. On the science side, the book will provide important new information to control engineers, electrical engineers, and scientists. The new data and insights will enable students to have a better grasp of the complicated advanced control with application to active power filters. In short, this book will mark a milestone of an integrative approach that is needed to better understand and better manage the emerging power electronics world.

Book Description

This thesis addresses the issues of filtering the harmonics in electrical grids using active power filters. Power converters are the main element of an active power filter. The performance of the filter greatly depends on the type of the converter, on the control system and on the modulation technique used to command the converter. This thesis focuses in three-level neutral point clamped converters which work as shunt active power filters to compensate the current harmonics. Firstly, this thesis makes an introduction about what is the grid quality and why is important to not have currents and voltages with significant harmonics. Secondly, we describe several converter topologies which can work as an active power filter. This description includes the well-known two-level converter and also different topologies of multilevel converters. Thirdly, we present the control system used in the studied converter. The control system includes the grid synchronization, the voltage and current loops and how we detect the current harmonics to compensate. Finally, we present some modulation techniques used in multilevel converters and the modulation used in the proposed active power filter. All the simulations included in this these have been performed using the software MATLAB SIMULINK and PLECS.

Book Description

This book deals with fuzzy generalized PI-control method for hybrid active power filter, and new injection circuit topology. In this supply current detection control strategy is used. With this approach of injection circuit topology, in power system harmonics compensation down by using low capacity active power filter. The fuzzy generalized PI-control method is used. In this control method two control units present: a generalized integrator control unit and fuzzy adjuster system. This control method is useful to any other active power filters; also it is less expensive compare with new technologies like FACT systems and it very effective in compensation of harmonics. Compare to other HAPF control methods fuzzy generalized PI-control method have the advantages of faster response and low error of harmonic compensation in distribution system. The MATLAB simulation result shows that the new control method is very effective in reducing harmonics.

Book Description

Maintaining a stable level of power quality in the distribution network is a growing challenge due to increased use of power electronics converters in domestic, commercial and industrial sectors. Power quality deterioration is manifested in increased losses; poor utilization of distribution systems; mal-operation of sensitive equipment and disturbances to nearby consumers, protective devices, and communication systems. However, as the energy-saving benefits will result in increased AC power processed through power electronics converters, there is a compelling need for improved understanding of mitigation techniques for power quality problems. This timely book comprehensively identifies, classifies, analyses and quantifies all associated power quality problems, including the direct integration of renewable energy sources in the distribution system, and systematically delivers mitigation techniques to overcome these problems. Key features: • Emphasis on in-depth learning of the latest topics in power quality extensively illustrated with waveforms and phasor diagrams. • Essential theory supported by solved numerical examples, review questions, and unsolved numerical problems to reinforce understanding. • Companion website contains solutions to unsolved numerical problems, providing hands-on experience. Senior undergraduate and graduate electrical engineering students and instructors will find this an invaluable resource for education in the field of power quality. It will also support continuing professional development for practicing engineers in distribution and transmission system operators.

Book Description

Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.
